TO ALL WHOM IT MAY CONCERN:

Be it known that I, CORNELIUS ISEnnIAN, of Unnton City, in the county of C1inton,and State of Iowa, have invented a. new and useful Improvement in Brick-Presses for Pressing Brick; and I do hereby declare thatl the following is a full, clear, and careful" description of the same, reference being had to the accompanying drawings, and the letters of reference marked thereon. l

The nature of my invention consists in so constructing the press that one motion of theworking-lever presses thebrick, and the movement of this lever backdiseharges the brick smoothly without any raping or gasing. lAlso, the same movementopens the mould to' receive the concrete or clay for a. new brick. Also, in so constructing the lid or cover to the mould, as that the movement of a lever up and down will easily open the cap or close it securely, as desired, thereby saving a great amount of time, and making a more perfect article `than in the ordinary way.

In the drawings, the same 1letters refer to the same parts, in whibh drawings- Figure 1 is an end elevation. Figure 2, a vertical section, showing discharge-rods, &c. Figure 3 represents a perspective view. Figure 4, side view, showing the pitm'an and Adischarge-rods.

Figure 5, section showing brick pressed, and discharge-rod in gear to force it out. New, to enable others to construct and use my invention, I will carefully describe its parts and construction. The letters refer tothe various parts as follows: l A represents the frame of press. B represents the cap or cover to mould-box. G represents the brick. .D represents the bottom of mould. E represents the lever toV operate the cover B. F represents the pitman to force the bottom up. H represents the sides lof brick-mould. .I represents a inovuhle fulcrum to operate press. K represents ashaft running through tho machine, and has a. square eii'd to receive the socket ofI lever T. L represents adjustable arms to work discharging-device. N represents shaft attached to pitman F. O represents slot in orm L to regulate throw of rods S. P represents slot in frame to regulate the cap or cover. R represents slot in discharge-rods for rest to slide in when the mould is opened for material. S represents rods for forcing out the brick after it is pressed. i T, the operating-lever of the press. I U represents rests that fit on shaft to press thelbrick, being attached to bottom of mould. V represents thc strap that contines pitmnn F to shafts N- and K. W represents a recess in frame to receivethe cap or cover B when a brick islto bc pressed. vX represents a rack, with teeth, to gear into the movable fulcrum J. Y represents the bottom of machine. Z reprcsentsa shaft that moves in the'grooves marked 2, and regulates the cover or cap P when opening and closing it. y

Now, the construction and operation of my invention are as iollows: I construct the frame A, and all the various parts of the machine, of any suitable material, of proper strength and proportion, und arranging the parts so as to work in the following manner:

The place to receive the material for pressing into brick is located in the toppart of the machine, and the bottom of this mould or place for materiel is made movable, and in the drawings is marked D.

' To fill the mould with material, place the device so that the bottom, D, 'will be in position, us shown at D', iig. 2.l The supports of this bottom, D, rest on the shaft N. Having filled the mould, and placed on "the cap or cover B, which isfrmly held in its place by shaft Z und notch W, and taking hold of the lever T., iig. y1, and bringing it down tothe position of T', dotted line, and the cog-gear in Jmeshixg into the rack X, and carrying the lower end of thepitman F from the inclino, as shown in fig. land fig. 2, to that shown in iig. 3 and fig. 5, which raises the shaft N as much ns the difference between the incline und the perpendicular, non', to gain .a

Vgreat pressure and more distance, the shaft K is put beyond the centre of J, asshown at K. tig. 1 and fig; 2,

and when the lever T is brought down 7to T', iig. 1,.the 'shaft Ii is directly over the centre of J, thereby, in passing from the point, as shown at K, iig. 1 und fig. 2,-to that of yK, tig. 3 and fig. 5, increasing the dist-ance of the movement of the shaft N, consequently raising the bottom, D.

It will bfeobserved here that the greatest pressure is just where it is wanted, for as the materiel is compressed, tlxe' leverage is increased by the pitnian F ond shaft K coming into a perpendicular line under the mould. The cap or cover B is operated as follows: The rod or shaft Z passes from the quadrant 2, through the .handle E, to the opposite side, to u similar quadrant;h .The handle E turns on a pin in an eye fast to frame,

rwith n. slot, sous to have a motion horizontally, as at P, iig. 2, so that by bringing thc handle E up to a level, us shown at gs. 1 and 3, the cup B will go into the catch W, which, with the 1rnd Z, holds it firmly while the brick is being pressed. To remove the cap, bring the handle down, and, by the motion given by the quadrant 2 and slot P, figxl, the cap is easily removed, and no injury clone to brick, as in other machines. A To discharge the brick from the mould, vil have invented the following method: I attach to the inside of tho truveiling-fulcrum J en arm, fitted by u slot on to shaft K, made fast toJ by means of a bolt-or screw in a 3101;, as at O, figs. 2 and 5. ,This slot allows the arm to bo ndjusted to iit the desirodlthrow to be given to the rodsS. These rods pass through or around the shaft N to the under side of the bottom of mould. When the brick is pressed, the arrangement will be as shown in iig. 5` By bringing the lever '.I beek to its iii-st position, the wrist in arm L willcatch in the socket, and, as the fulcrum J turns back, this arm L will force the rods S up, thereby raising the bottom of the mould to the top, as shown at D, fig. 2, leaving the brick free and clean, as at. 0g. 2. The position ofy the-se rods will be as indicated in iig. 2. y

To set'thc machine to make another brick, I have but to press against the rods S and the socket on the wrist slipsl oli', and the wrist in arm Lne longer holds up the rods S and bottom D, but by their own weight the rods S slide down on this wrist in the slot R, as indicated by dotted lines in g. 2.

I fnd a great advantage in my device to cover thc mould, as et 13. 'lhe first motion, after the brick is` pressed, is a sliding one, by which the adhesion ofthe material te the cover B is ovcrccme smoothly, leaving the top of brick smooth und fuir.

what I claim as'new, and desire to secure by Letters Patent, is A The combination and arrangement of cap B, shafts N and K, pitman I, rods S S, arm L, and travellingfulcrum J, when constructed, arranged, and operating substantially as and for the purpose herein sot forth.
